Instead of calling the grep/sed pipelines for each file, build the

As Anders correctly pointed out in I7d8f84b2e, constantly resetting state will
turn init_dissection into a bit of a hot path. Especially as we will already
bear the overhead of switching files, we don't want to fall any further behind
than we have to.
This change includes three unrelated optimizations that reduce the cost of
init_dissection by about 40% as measured by callgrind:
- only initialize ares/ADNS if that preference is enabled (this of course only
applies if you specify -n to tshark or otherwise disable the preference)
- use memcpy instead of a loop in sigcomp UDVM init
- use memcpy instead of a loop in bootp dissector
The only remaining obvious hot spot in this path is reassembly_table_init since
it is called by so many dissectors. Suggestions (perhaps to get rid of the
GPtrArray) welcome.
Oh, and one other change to use g_strerror instead of strerror as insisted
upon by the API pre-commit hook.

Since DTLS and TLS do not differ in handling ClientKeyExchange and
ServerKeyExchange, its dissection got moved to ssl-utils. The code is
based on the SSL dissector, with header field names adjusted to the
DTLS ones (those got capitalized). Besides a version difference (for
signatures), the header field and function names, the DTLS and SSL code
are equal (this is verified).
This patch refactors the dissectors for DHE_RSA and ECDHE to make use of
a common function to dissect the signed_params field. All offset
tracking is also removed in favor of exception handling by the
proto_tree_add_item function. Occurrences of proto_tree_add_uint are
also replaced by proto_tree_add_item for simplicity.
After those changes, the SKE dissector for DH key exchanges is updated
to handle the mandatory signature field in TLSv1.2, using the newly
added function. (bug 9208)
Another bug occurred after the length check removal, pre-TLS and
OpenSSL's old DTLS implemenation do not include a vector length in
the CKE. This is now also fixed. (bug 10222)
